Energy-saving wear-resistant dual-layer cold water roller

Abstract

The invention discloses an energy-saving wear-resistant dual-layer cold water roller, comprising an outer barrel, an inner barrel, two shaft heads, two connection tubes and two seal heads; the two shaft heads are arranged at the two ends of the outer barrel; the shaft heads are provided with an axial water passage not open to a bore of the inner barrel; the two connection tubes are radially arranged at the inner two ends of the inner barrel; the two ends of the connection tubes are fixedly connected to the ends, extended into the seal heads, of the shaft heads and to the inner wall of the inner barrel; the inner two ends of an interlayer are provided with partitions facing the seal heads in spaced manner; the facing partitions form a cooling chamber; the axial water passages of the shaft heads are communicated with the cooling chamber through the connection tubes; the partitions and the close ends of the seal heads form heat-insulating cavities filled with heat-insulating filler. The energy-saving wear-resistant dual-layer cold water roller is further characterized in that spiral slabs are spirally arranged in the cooling chamber to form spiral guide channels; the surface of the outer barrel is provided with a wear-resistant layer; water outlet parts, communicated with the cooling chamber, of the two connection tubes are in diagonal arrangement. The energy-saving wear-resistantdual-layer cold water roller is good inn cooling effect and wear resistance, long in service life, low in heat loss and significant in energy-saving effect.

Description

technical field [0001] The invention relates to the field of textile, printing and dyeing machinery and equipment, in particular to a double-layer cold water roll. Background technique [0002] Double-layer cold water rollers for textile, printing and dyeing generally include an outer roller, an inner roller, two shaft heads, two nozzles, and two heads. The outer roller is coaxially fitted on the inner roller, and the two heads are respectively It is fixedly connected to the left and right ends of the outer roller and the inner roller to form a sandwich between the outer roller and the inner roller. This kind of double-layer cold water roller realizes the cooling function between the interlayers when used, and the cooled water can be used, but it has the following defects: Although it is cooled by the cooling water between the interlayers, part of the heat is still transferred to the sealing head On the one hand, it is transferred from the head to the shaft head, which dete...

This kind of double-layer cold water roller realizes the cooling function between the interlayers when used, and the cooled water can be used, but it has the following defects: Although it is cooled by the cooling water between the interlayers, part of the heat is still transferred to the sealing head On the one hand, it is transferred from the head to the shaft head, which deteriorates the use environment of the bearing on the shaft head; on the other hand, a large amount of heat is lost through the head
